Is atheism a way to escape from responsabilities of religions?

I think atheism in a way requires more responsibility because you have to make your own decisions, and answer to yourself rather than having a set of rules to follow. It requires actually considering what you're doing and why. I've known a lot of atheists who were actually very moral people. I do think that many people who are atheist are those who don't depend on social ties that are often held together by religious bonds. Many of them are well-educated people who decided after much learning and considering that they couldn't accept what religions were telling them. As for where they live, I think in some countries religious freedom is more rampant, and of course those countries would have a higher share of atheists because people would feel more allowed to question religion. Reading this, I wonder if people will think I'm atheist, which I'm not. =p
